In this guide, we will be interfacing NPN Pulse Output Anemometer Sensor with Arduino and measuring the Wind Speed. An anemometer is a device used for measuring wind speed and direction. It is also a common Weather Station instrument.
In one of our previous projects, we measured Wind Speed using the Adafruit Anemometer sensor & also display the Wind Speed in Gauge on TFT LCD Display. But Adafruit Anemometer is an analog anemometer and requires a power of more than 7V for operation. Therefore we will be using a digital Anemometer in this project which has NPN Pulse Output. The NPN pulse output anemometer result is good & are also cost-effective & they operate at 5V only.
In this project, we will interface NPN Pulse Output Anemometer with Arduino & display the measured wind speed on a 16×2 LCD Display. This anemometer is capable of measuring wind speeds up to 70 m/s or 156 mph which should be adequate for our location.
